  • TM4C123GH6PGE: I2C5 SDA Pulled low after Pin Configuration

    Resolved
    Part Number: TM4C123GH6PGE Hello, We're having some trouble using I2C5 on the TM4C123GH6PGE. When the Pins are configured as I2C, the SDA line is pulled low and subsequently stays low... resulting in the bus always being busy. We have used the same TIVA…

  • TM4C123GH6PGE: Is there a python/c-code implementation for DFU via the build in ROM bootloader?

    Resolved
    Part Number: TM4C123GH6PGE Our TI MCU is connected via UART0 to a IoT board. We like to do a firmware update via the ROM bootloader through the IoT board. The IoT board runs a self build Linux. So we can't use the windows flashing tool. Is there a…
